Thank you for that hint!Will check that tomorrow! I tried the LMDE 2012-04 live CDs and thought they are using the 3.2 Kernel already? With LM 13 Mate, the Card Reader is working fine!!Maybe I was wrong again, sorry... and thank you for your patience!!

Ok, well maybe i don't have a realtek... I thought i did. Perhaps AlbertP can explain something if he/she has understanding of the problem. If this is simply a matter of support inherent in the kernel, then could not one simply install the liquorix kernel? Or does this require the installation of a kernel and a separate driver to support the realtek card reader as well?

The OP has "ID 0bda:0139 Realtek" in lsusb output, so a Realtek RTS5139 cardreader. This one is supposed to be working in Linux 3.2 and later: so it should work in Mint 13 and in latest LMDE. For some reason, in LMDE's 3.2 kernel, it's not working yet - but I think, next time LMDE gets a kernel update, it will work.

@ lizbeth: If you want to know what cardreader you have, insert a card into it, and run lspci and lsusb. One of them should display the cardreader. I for example have a Ricoh cardreader in lspci on my laptop, and an Alcor Micro one in lsusb on my desktop.
